Jiaming Yuan ef11b024e8 Cleanup data generator. (#8094) 
- Avoid duplicated definition of data shape.
- Explicitly define numpy iterator for CPU data.

Jiaming Yuan 5156be0f49 Limit max_depth to 30 for GPU. (#8098) 2022-07-20 12:28:49 +08:00
Jiaming Yuan 8bdea72688 [Python] Require black and isort for new Python files. (#8096) 
* [Python] Require black and isort for new Python files.

- Require black and isort for spark and dask module.

These files are relatively new and are more conform to the black formatter. We will
convert the rest of the library as we move forward.

Other libraries including dask/distributed and optuna use the same formatting style and
have a more strict standard. The black formatter is indeed quite nice, automating it can
help us unify the code style.

- Gather Python checks into a single script.

Jiaming Yuan 2365f82750 [dask] Mitigate non-deterministic test. (#8077) 2022-07-19 16:55:59 +08:00
Jiaming Yuan 4083440690 Small cleanups to various data types. (#8086) 
- Use `bst_bin_t` in batch param constructor.
- Use `StringView` to avoid `std::string` when appropriate.
- Avoid using `MetaInfo` in quantile constructor to limit the scope of parameter.

Jiaming Yuan dae7a41baa Update Python requirement to >=3.8. (#8071) 
Additional changes:

Jiaming Yuan 8dd96013f1 Split up column matrix initialization. (#8060) 
* Split up column matrix initialization.

This PR splits the column matrix initialization into 2 steps, the first one initializes
the storage while the second one does the transpose. By doing so, we can reuse the code
for Quantile DMatrix.

Jiaming Yuan a5bc8e2c6a Fix mypy error with the latest dask. (#8052) 
* Fix mypy error with latest dask.

Dask is adding type hints to its codebase and as the result, checks in XGBoost can be
performed more rigorously.

- Remove compatibility with old dask version where multi lock was missing.
- Restrict input of `X` to be non-series.
- Adopt latest definition of `Delayed`.
- Avoid passing optional `host_ip`.
- Avoid deprecated `worker.nthreads`.

Jiaming Yuan fdf533f2b9 [POC] Experimental support for l1 error. (#7812) 
Support adaptive tree, a feature supported by both sklearn and lightgbm.  The tree leaf is recomputed based on residue of labels and predictions after construction.

For l1 error, the optimal value is the median (50 percentile).

This is marked as experimental support for the following reasons:
- The value is not well defined for distributed training, where we might have empty leaves for local workers. Right now I just use the original leaf value for computing the average with other workers, which might cause significant errors.
- Some follow-ups are required, for exact, pruner, and optimization for quantile function. Also, we need to calculate the initial estimation.
